Cicadas, those buzzing insects that emerge periodically, are actually harmless creatures. They do not bite or sting, so you don’t have to worry about any pain or discomfort from them. As a gardening and landscaping expert, I have encountered cicadas many times, and I can assure you that they pose no threat to humans.
One of the most fascinating things about cicadas is the loud noise they produce. Male cicadas create this noise by vibrating their tymbals, which are drum-like structures on their abdomen. They do this to court and attract female cicadas. The sound can be quite ear-shattering, especially when there are many cicadas gathered together.
Cicadas have a unique life cycle that involves spending most of their lives underground. They stay in the soil feeding on tree roots for several years, typically either 13 or 17 years depending on the species. Then, they emerge as adults in large numbers, a phenomenon known as a “cicada emergence” or “cicada outbreak.”
During these emergences, the ground and trees can become filled with cicadas, creating a spectacle for both nature enthusiasts and curious onlookers. While their sheer numbers can be overwhelming, it’s important to remember that they are harmless insects.
It’s worth noting that cicadas are not poisonous or venomous either. They do not possess any toxins that could harm humans or pets. In fact, cicadas are often considered a delicacy in some cultures and are consumed by people as a source of protein.
In terms of gardening and landscaping, cicadas may have some impact on trees and plants. Female cicadas lay their eggs in small slits they make in tree branches. This can cause damage to the trees, leading to the withering of some branches or even tree death in severe cases. However, this damage is usually limited to a small percentage of trees and is not a cause for major concern.
To protect your trees during a cicada emergence, you can cover them with nets or other physical barriers. This will prevent the female cicadas from laying their eggs on the branches. Alternatively, you can focus on maintaining the health of your trees by regularly watering and fertilizing them, as healthy trees are more resilient to cicada damage.
Cicadas do not bite, sting, or pose any danger to humans. They are fascinating creatures that play a unique role in nature. So, the next time you hear their distinctive buzzing sound during a cicada emergence, take a moment to appreciate these remarkable insects and the natural cycle they are a part of.
